Abstract: Circuits for full duplex bi-directional differential communication via a single conductor pair. A transceiver for full duplex differential communication over a single conductor pair includes a differential driver, a polarity neutral receiver, and receiver output circuitry. The differential driver is to drive the conductor pair. The polarity neutral receiver is to detect signals present on the conductor pair. The receiver output circuitry is configured to determine a logic value to be output by the transceiver as received via the conductor pair based on an output of the polarity neutral receiver and a logic value driven onto the conductor pair by the differential driver.

Abstract: Two CAN bus transceivers utilized in a single integrated circuit package with the CAN bus connections between the two transceivers being inverted. Thus, one transceiver is connected to the CAN bus high and low lines while the other transceiver is connected to the CAN bus low and high lines. Both transceivers power up in a standby condition and each transceiver is monitoring for wake up signals on the CAN bus. The transceiver that is correctly connected to the CAN bus detects wake up signals. When the wake up signals are detected at that transceiver, that transceiver is brought to full operating state and the other transceiver is placed in a full standby condition. Additional input resistance is provided with each transceiver to maintain the proper input resistance for the integrated circuit.
